vision of its delivery of management leader naturally tends to disappear upon the product to the customers, since focus continually shifts to the next test coverage to insure that defective product is not shipped will also be overlookedunderestimated by such managers. Design techniques in the layout that contribute to greater yield will not likely be on their radar screen as their focus will be...

This research aimed to analyze the damaged products at PT. SIGNORE, Tangerang, Indonesia. A Fish Bone Diagram was drawn determine factor that causes defective products. Then, an action plan including concept of Five M checklist, 5W + 1H (What, Why, Where, When, Who, How) and seven new tools corrective plan, labor, machinery, materials, methods environment were developed. The purpose this study ...

A graph G is (j, k)-colorable if its vertices can be partitioned into subsets V1 and V2 such that in G[V1] every vertex has degree at most j and in G[V2] every vertex has degree at most k. We prove that if k ≥ 2j + 2, then every graph with maximum average degree at most 2 ( 2− k+2 (j+2)(k+1) ) is (j, k)colorable. On the other hand, we construct graphs with the maximum average degree arbitrarily...

In this research, we consider an application of the Bayesian Inferences in machine replacement problem. The application is concerned with the time to replace two machines producing a specific product; each machine doing a special operation on the product when there are manufacturing defects because of failures. A common practice for this kind of problem is to fit a single distribution to the co...

Traditional economic manufacturing quantity (EMQ) model addressed that the perfect production for product. However, there possibly exists the defective product in the manufacturing process. Hence, it is necessary to include the quality cost in the EMQ model. In this paper, we propose a modified EMQ model with quality loss and inventory cost. By solving the modified EMQ model, we can obtain the ...

In statistical quality control, product acceptance determination is an important problem for producer and consumer. In practical, particularly more than one quality characteristic must be simultaneously considered to improve the product quality because of the product design. In this article, we investigate the lot sentencing problem for normally distributed process with one-sided specification ...

Ten novel methylotrophy genes of the facultative methylotroph Methylobacterium extorquens AM1 were identified from a transposon mutagenesis screen. One of these genes encodes a product having identity with dihydrofolate reductase (DHFR). This mutant has a C(1)-defective and methanol-sensitive phenotype that has previously only been observed for strains defective in tetrahydromethanopterin (H(4)...
